Fig. 3: Modern, Holocene, and future mass-balance calculations comparing rates of sediment delivery against the mass required to offset sea-level rise and subsidence.
A Summary of the mass-balance scenarios, showing input values for sediment supply and sea-level rise and the calculated outputs for Δ Mass and f(supply). Calculations of required mass for each scenario can be found in Table S4. B An explanation of the calculated terms, the conditions for each Δ Mass case, and the data sources are provided along with C, a schematic diagram of the mass-balance model for the delta. The Holocene: 10–8 ka scenario considers only the high sediment demand case, as the whole delta aggraded in response to rapid sea-level rise during this period.
